In particular, she found an unbalanced pair of chromosomes in male cells, and she named these structures "heterochromosomes." Similarly, American geneticist E. B. Wilson worked with several ...

Meanwhile, subsequent research identified CENP-B as a protein that binds to a simple sequence repeated many times in centromeric DNA. The centromeres of human chromosomes are heterochromatic ...
